Probably either the databank was not up-to-date or the indexes were not
up-to-date (and hence pointing to wrong entries). I know by experience
that keeping a server with HUGE databanks up-to-date is hard...
I tried, at Indiana it still does not work, at Pasteur and also at our
site (http://www.be.embnet.org/srs) you get what you want.
GENBANK:AE015854 (similar to)
GENBANK:HSBA18I14 (similar to)
GENPEPT:AE015854_2 (similar to)
Note : if you click on "Standard" or "Extended" you can search
specifically for X61499 in the "Accession Number" field.
